namm.,

To all whom z'tm ag concern Be itknown that. I, HANS BUcHNEn, a'

subject of the German Em eror, and residing at Munich, Bavaria, ermanEmpire, have invented certain new *and useful Improvements in Boot andShoe Trees, of

' is illustrated in the accompanying drawing.

j `Figures 1 and 2 are perspective views ofthe body and heel portions.of thetreere-' spectively'. ,Fig 3 s a erspective View of the assembledtree, exhiiting in particular the sole thereof. Fig. 4: is a horizontalsection showing the tree applied to a shoe, Fig. 5 is 'a similar View toFig. 3, but drawn to a smaller scale and showing the two members of thetree separated, the channeling s 'moreover being omitted for the sake ofclearness in the drawing.

The tree comprises a suitable n mber of 'matching Sections, there beingin the particular embodiment illustrated only two such, viz. abody-portion a' and a heel-portion b, fitted thereto with tongue andgroove Both sections a, 'b, are hollow,

a receptacle to contain hoteating-liquid, or some me-- joint e, e. eachconstituting water or other dium which generates heatby chemicalreaction. The two parts a, b, may be advantageously made of aluminium,or some other light but strong material, and each tnay-be furnished withan openable cover of any suitable description, or gnay be closed over atthe top and be there provided' with a screw-stapper or the like inwell-known manner. The entire surface of the two scctions a, b, (Withthe exception of the joining v 'faces where the tongue and groovee e,are" located)' is fiuted, channeled or grooved, in

such manner as to present an assemblage'of" closely contiguous passagesc for the flow' of:

air and vapor. The ribs or ridges d sepa- Specificationofette's Patent.i Application filcd-August 27,1912. Scrial No. 717,326;

rating the individual'gr'ooves care shown as being` nterrupted at f onthe .sole of the tree, whereby the various ducts c are'brought intocommunication. When the tree 'is ap- 'pled to a shoe,

the vapor flowing up the passages c forms between the tree-walls andshoe g (Fig. 4) an insulating. layer, Which is only interrupted by thenarrow ribs d which separate adjacent groo'ves' Thuswith my improvedtree the vap`or which 'rises during drying of the shoe has a. freepassage for escape from all parts and the warm air in the ducts of thearticle, j

it were, a jacket which serves constitutes, as

the walls of the shoe. A particular advantage of the improved groovedconstruction is thus seen to be that although perfect support isafl'orded to .the material of the shoe at all places, for the purpose ofpreventin'g creasing and maintaining an even surface' and regular shape,`vapor can pass off 'at every art 'and warm air can act directly andw1th` full effect on the material, which is uncovered by anyjinterveningsurface, the ribs d -being so narrow as to form .no materialobstruction. The new tree is,

therefore, especially suited for fine or deli- .to equ alize the heatradiated by the different" parts of the tree and impart it uniformly tocate leathers, such 'as kid, patent leather, and

the like; a

It will be observed that the improved tree i's especially adapted forthe use of travelers, tourists, etc., since the Sections can be uti-'`lized as cooking or'drinking vessels, as hot*- Water bottles,-or. thelike. j

Having thus described my invention, I

r claim as new- 1. A boot and shoe tree whose body co stitu tes a liquidcontainer and whose surface is covered with grooves separated by narrowribs, which extend' upwardly from the 4 sole, 'Where they run substantially parallel with each other in trainsverse direction.

2. A boot'and shoe tree whose body conl stitutes a liquid containerandwhose surface s covered with-:groot es separated by narrow ribs,'which extend. upwardly from the sole,

where they a're directed. substantially at' right l'angles to thelongitudinal 4 sole-axis, along `whch they are interrupted.

3. ,A boot or shoe tree whose body com stitutes a liquid container andwhose -surthe sole-axis and each leading to one of the vface isv,covered With grooves separated by said grooves, V narro w` ribs,-extend'ng upwardly from the In testimony whereof I aflix my Signaturesole, Which latter presents a assage located in presenceof twowitnesses.
